atoi equivalents?

What is the most efficient or recommended way to parse numbers in Mathematica?

I can use ToExpression["1234"] and it will return the number.
But this won't do, because I could be scraping un-trusted data and the
above could lead to an injection of code.
I could also use something like this: ToExpression[StringCases["1234",
x1 : NumberString ~~ ___ -> x1]]
but then I have to add error checking and whatnot.
I suppose I could write a simple MathLink program which implement
atoi, atol, etc.

All of these solutions seems like a lot of overhead.  Anybody have a
better idea?

Thanks,

Michael
